Hypersonic retro propulsion for reusable launch vehicles tested in the H2K wind tunnel

CEAS Space Journal, 2022
In the frame of the RETALT (RETro propulsion Assisted Landing Technologies) project, the aerodynamics of reusable launch vehicles reentering the atmosphere and descending and landing with the aid of retro propulsion are studied.

The Measurement of Radar–Plasma Signatures in a Hypersonic Shock Tunnel: Simulation and Experiment

IEEE Transactions on Aerospace and Electronic Systems, 2023
The plasma sheath that forms around a body in hypersonic flight can change the radar signature substantially. The prediction of radar–plasma signatures, however, is complex, since it incorporates aerothermodynamics and electromagnetics and requires a ...
